Let me be more specific. We have redo logs in WAL that handle a case of
the system crashing during the day. That is handled automatically.
What we don't have is a way to recover from a disk failure in the middle
of the day. For that, we will need point-in-time recovery.
I am starting a data recovery article this week which should cover these
options.
